10:58 ohwow: What sorting algorithm does the (sort) function use?
11:03 jonrafkind: most likely quicksort or mergesort
11:04 jonrafkind: Based on "Fast mergesort implementation based on half-copying merge algorithm",
11:04 jonrafkind: Cezary Juszczak, http://kicia.ift.uni.wroc.pl/algorytmy/mergesortpaper.pdf

11:16 ohwow: this is too advanced for me
11:16 ohwow: i wrote a mergesort and it's just sooooooo slooow
11:16 lucian_: ohwow: profile it
11:17 ohwow: because i heavily rely on gc
11:17 ohwow: lucian: how can i do that?
11:17 lucian_: then the gc isn't great

12:08 ohwow: hm
12:08 ohwow: what might be the problem?
12:09 bremner: require in the repl doesn't really work
12:09 bremner: afaik
12:09 ohwow: well I have #lang racket/gui on top
12:09 ohwow: and racket/gui should load racket
12:11 jonrafkind: are you on the command line or in drracket?
12:11 bremner: hmm. that works here. What version of racket?
12:11 jonrafkind: that require works for me
12:11 jonrafkind: i have 5.1.1.5 fwiw
12:11 ohwow: bremner: 5.1
12:12 bremner: hmm. it worked for me with 5.1.1 every way I could think of testing it.
12:12 ohwow: strange

12:20 bremner: eli: ok
12:20 bremner: in fact this example works fine in the repl for me
12:22 eli: Yeah, it just didn't exist in 5.1.

22:19 neilv: aha. i see that drracket's editor already works in the way i was thinking of doing for the new emacs mode, with respect to sexp movement and quote
22:20 neilv: if the buffer with point is "a '|(b c) d" (where vertical bar character is point), and you do a right-sexp movement, you get "a '(b c)| d"
22:21 neilv: if you immediately do a left-sexp movement, you get "a |'(b c) d" (i.e., you're now before the quote rather than after)

22:54 eli: neilv: Changes like that are likely to make me avoid switching...
22:54 eli: I can see it leading to some weird interactions, then me remembering that something is wrong and trying to avoid it, then giving up on the whole thing...
22:55 eli: A good example for that is how they made shell output behave wrt hitting the `end' key, which infinitely annoys me.
22:57 neilv: well, drracket agrees with what i was already thinking was the right way :)
22:59 neilv: hm. drracket default for comment color is still yellow-snow.  i really preferred the cyan
23:00 neilv: i think it changed to yellow-snow when check-syntax started using multiple shades of blue for identifiers
